Catalog No. 289B Screw Lift Conveyor for Efficient Elevation When Your Handling Problem Calls for Elevating Bulk Materials
...elevate, convey, Application Versatility and Engineering Capabilities The Screw-Lift Conveyor is ideal for elevating, distributing and reclaiming an exceptionally wide range of bulk materials efficiently in a minimum of valuable floor space. Generally speaking, if your material is not extremely abrasive and can be conveyed in a horizontal Screw Conveyor application, it can be elevated in a Screw-Lift Conveyor... and without many of the problems inherent in other types of elevating equipment. The Screw-Lift Conveyor can be used in several configurations for a variety of materials, and Screw Conveyor Corporation has a staff of experienced application and product engineers to assist you in any special design or application requirements.

distribute, recycle, reclaim Efficient Design The Screw-Lift is not merely a tubular screw conveyor operated in a vertical plane. The expanded feeder junction s special conveyor screw flight arrangement with high speed rotation provides the elevating action rather than extruding the conveyed material through a solidly filled tube. Important Advantages Flexibility in design and arrangement. Available in basic models and 3 sizes. Highly efficient transfer of materials from horizontal to vertical. Savings of valuable floor space with less overall height requirement. Material discharge in any direction. Conveying Principle The conveyor screw operating in a vertical portion of the Screw-Lift is constructed so that it gets the material started upward most efficiently. The horizontal conveyor screw in those units incorporating a feeder is designed and synchronized from a speed and rotation standpoint to provide a uniform and smooth transfer of material from horizontal to vertical. Ease of Installation The Screw-Lift is compact and requires little floor space. Each unit is assembled and test operated at the factory. It is then matchmarked, disassembled and crated for shipment. Assembly in the field requires only following the matchmarks and installation and operating instructions supplied with each Screw-Lift. Materials of Construction Screw-Lift Conveyors are made of carbon steel as standard. They can also be constructed of series 300 and 400 stainless steel for special applications. They can be hot dipped galvanized for certain corrosive conditions. Abrasion resistant steel flights can be provided. Candy manufacturer employs Screw-Lift in ingredient distribution system. This stainless steel, quick opening type Screw-Lift handles ice cream mix. Outdoor installation shows two Screw-Lifts at large feed processing plant. 3 Installation illustrates Screw-Lift s compact arrangement with other equipment.

To insure good performance they are checked for straightness and run-out using a dial indicator. The stabilizer bearings keep the conveyor concentric and provide for a smooth running unit. In addition, these bearings, located at proper intervals, allow for greater heights of lift. One of the outstanding features of the Screw-Lift is the expanded tapered feeder junction. The conveyed material is transferred most efficiently from horizontal to vertical flow by the 90 degree side opening into the expanded feeder junction that is incorporated with a special conveyor screw flight arrangement for speedy pick up and elevation.

of bulk materials The Screw-Lift is constructed with a tubular housing. The housing is fabricated to provide a 1/4" nominal clearance between the periphery of the conveyor screw and the inside of the housing. Replacement of screws requires some disassembly. Types, Sizes and Capacities Types C, G and J feature a horizontal feeder screw. This provides the controlled feeding that must be adapted for the vertical elevation of material. Types E and H are gravity fed and can be used when handling materials that are of a granular nature and where the flow of material is governed or controlled by preceding equipment such as another conveyor, vane feeder, etc. Under normal conditions, Screw- Lifts will handle the following capacities on most materials. On certain dry, free-flowing materials, the capacity can be significantly increased. Screw-Lift Diameter Inches Nominal Rated Capacity Cu. Ft. Per Hour 6" 300 9" 1000 12" 200 With a full knowledge of your conveying needs, our Engineers will design a Screw-Lift for your particular requirements. The expanded feeder junction provides for 0% more capacity to relieve choking, back-pressure and material degradation. The quarter-segment opening permits exact loading, but no overloading, of the Screw-Lift. Slip couplings permit quick removal of any conveyor section. Note the stop pin which holds the coupling in readiness. Split stabilizer bearings eliminate whip and vibration and assure quiet operation whether the unit is loaded or empty. The feeder screw is coordinated with the vertical screw to ensure high material transfer efficiency..
TYPE C Type C Screw-Lift is equipped with a horizontal feeder screw that is synchronized with the vertical screw for proper feeding at the proper rate. The bottom drive unit is equipped with roller bearings and cut forged steel gears running in a continuous oil bath. Both the horizontal and vertical conveyors are operated with one motor and drive. The length of the horizontal and vertical portions of the Screw-Lift are fabricated to meet individual requirements (minimum lift height 8'8"). DIMENSION DATA DIAMETER 6-in. 9-in. 12-in.
